WRT54g Free Upgrade

I have a wrt54g version 5 router and need to upgrade it to work with my new Motorola sb6141 modem and Windows 7. Linksys no longer provides free upgrade support. Is there anything I can do at this point?

If you are using a WRT54G, I strongly recommend the DDWRT open source firmware, you'll get more bang for your buck. Heck that firmware is the best reason to stick with the WRT54G instead of upgrading to an 802.11N router.

I am going to recommend Tomato firmware over DD-WRT. It is still
aggressively updated and the interface seems a lot easier to use as opposed
to DD-WRT. If you don't mind a little extra work (the website is in
Polish), I especially recommend the Shibby mod, if supported by your router.

Brett is right about firmware being available free, and the other respondents that the firmwares they suggest are free as well.

I go back to the question, why are you upgrading the firmware? What about the modem and Windows 7 makes you change the router firmware? It is hard to make a recommendation without knowing what you are trying to accomplish.

Go to linksys website and look at the requirements for such upgrade maybe you just have to pay for that for some tokens and that's the Only way I can help you on this. To your present configuration you need that all.
